The pXRF Friday seminar being held in Brisbane 13 November has received some fantastic funding from REFLEX to allow AIG to offer students and unemployed ten free registrations.  Please tell your student and unemployed colleagues and friends (who also need to be AIG members)  about this offer.  First in – first served.  Contact Rod Carlson prior to registering.

Free pXRF certification training is now also being offered by Olympus on Thursday 12 November 9am-1pm at the AMC offices in Brisbane.  Again, please email Rod Carlson to reserve a place before Wednesday 11 November. This is an offer too good to turn down for anyone contemplating minerals exploration as a potential career.

Exploration Results: Reporting Sulphide Mineral Observations in Drilling Intersections

Correspondence has been received from members in recent weeks regarding the description and reporting of sulphide mineralisation in drilling samples. This relates, essentially, to sulphide intersections being reported without any attempt to:

  1. Describe the nature of sulphide mineral occurrence (e.g. massive, disseminated, in veins, forming veins or bands concordant or discordant with bedding or a penetrative foliation observable in the host rock);
  2. Identify the minerals observed; or,
  3. Estimate the abundances of any sulphide minerals observed.

Estimation of the proportions of mineral species present in a sample, where individual grains or crystals are visible in hand specimen, is considered to be:

  1. a skill in which geologists are trained during the course of their university studies in, but not confined to, mineralogy, petrology and economic geology;
  2. an aspect of exploration and mining work in which geologists may be readily and meaningfully trained; and,
  3. work that may be guided by published resource materials (e.g. mineral percentage estimation charts published in the AusIMM Field Geologists’ Manual and numerous other publications, including reference cards that may be readily accessed and referred to by geologists undertaking sample examination and description (Figure 1, Figure 2).

Estimates by experienced, competent geoscientists are considered to be reliable and reproducible semi-quantitative estimates of the abundance of minerals present in a sample.  Visual estimates of sulphide mineral abundance should, however, never be considered a proxy or substitute for laboratory analyses where metal concentrations or grades are the factor of principal economic interest. Visual estimates also potentially provide no information regarding potential impurities or deleterious physical properties relevant to valuations of some mineral commodities such as graphite and many industrial minerals. Where visual estimates are reported, Competent Persons should provide an indication of when more substantive and reliable data in the form of laboratory analyses will be available.

Further, the ability to identify economically significant minerals, comprising either a mineral of value or a potentially deleterious constituent is considered to be a required skill possessed by geoscientists acting as Competent Persons for the commodity and style of mineralisation that forms the subject of any announcement or statement of Exploration Results, Mineral Resources or Ore Reserves issued in compliance with the JORC Code (2012).

Not adequately describing mineral species present, their relative abundances and the form in which they occur when their presence in samples is included in announcements and reports of exploration results may be considered not to comply with the underlying transparency and materiality principles of the JORC Code (2012) that may constitute a breach of the Code.

The correspondence received does not constitute a complaint against any Member.  The issue is, however, one within the remit of the AIG Complaints Committee to review, consult with members in relation to, and issue advice and guidance to Members.

Future failure to adequately address these requirements will expose Members acting as Competent Persons for statements of Exploration Results, Mineral Resources and Ore Reserves to complaints of being in breach of the JORC Code (2012), that may result in complaints being referred to AIG’s Ethics and Standards Committee.

Aon_LogoAon Benfield is seeking candidates for its 2015 Graduate Program.

Few geoscientists may be aware of career opportunities offered in the insurance industry, in fields including catastrophe management and risk assessment, even though geoscientific skills are widely called upon in prediction, management and remediation of natural hazards, to the point where many recognise this field as a specialised geoscience discipline.

Aon is a leading global provider of risk management, insurance and reinsurance brokerage, and human resource solutions. Aon considers their broad view of two of the most important issues in our economy today: risk and people as a key advantage. Utilising this advantage, Aon is driven to empower economic and human possibility for clients, colleagues and communities around the world.

Aon Benfield makes unparalleled investments in local and regional Talent Acquisition and Management. Since its inception, the graduate development program has become a cornerstone of this activity.

Aon Benfield Analytics offers clients industry-leading catastrophe management, actuarial, rating agency advisory and risk and capital strategy expertise. Together with our leading broking teams, it helps clients fully consider the capital, income, regulatory and rating agency implications of all risk transfer transactions. Our Impact Forecasting team develops tools and models that help our clients understand the financial implications of natural and man-made catastrophes around the world.

Geoscientists are amongst the key disciplines sought by Aon to work in this area.  

In all, the company’s team of 500 comprises  actuaries, scientists, volcanologists, seismologists, hydrologists, climatologists, meteorologists, statisticians, engineers, capital modellers, programmers and risk specialists.

Using our Sydney operation as a key hub for regional talent development, our Graduate Program offers a structured 12 month development opportunity for recent graduates or final year students in Actuarial Studies.

Aon’s Graduate Program

The 12 month programme is oriented around 4 distinct semesters, providing you with a development platform to accelerate your learning through structured classroom training, on-the-job learning, mentoring and assisted self-learning.  We will also provide study assistance, study leave and exam leave to support industry accreditation and professional qualifications.

Participants in Aon’s Graduate Development Program help to measure Aon client’s risk by applying complex techniques such as catastrophe modelling, exposure modelling and experience modelling. Participants are introduced to the use of dynamic financial analysis and capital modelling to advise our clients on a range of capital mechanisms they can apply to effectively manage their risk.

Who are Aon looking for?

Our Graduate Development Program ideally suits:

  • Australian nationals with a keen interest in and affinity with Asian culture
  • Asian nationals who possess working rights in Australia for the duration of the program, and who are open to undertaking future roles in AON’s regional APAC offices

To meet the selection criteria, candidates will demonstrate the competencies, skills and academic achievements below:

  • Graduates/ final year students in Actuarial Studies
  • Analytical mindset aligned with strong numeracy skills
  • Strong critical thinking and attention to detail
  • Excellent communication skills
  • A keen interest in building a career in the insurance/ reinsurance sector

AON Culture & Benefits

With close to 1600 employees, we are the largest organisation of our kind in Australia. Globally, Aon have an employee base of 69,000 people working across 120 countries.
